I love the wallpaper designs at Flavorpaper (a brooklyn based company) and they do custom stuff, too.

This is a canadian company that offers custom wallpaper for residential and commercial needs. They are in Toronto and Vancouver, really cool :) I know of 2 or 3 other online stores that offer the same, its always a question of budget since (can be between 35-55 per square f) Hope this helps! ROLLOUT is a creative studio that designs and prints custom single, or low run wallpapers.

Rather than traditional wall paper, may I suggest Blik wall graphics. Blik wall decals - Me, Myshelf & I created the illusion that you're well-read. Turn any room into a library with these easy to install vinyl decals.
